Optimized Electrical Stimulation Using a Spray-Printed Conductive Electroceutical Patch for Accelerated Wound Healing...

Area of Science:

• Biomedical Engineering
• Regenerative Medicine
• Wound Healing Research

Background:

• Diabetic wound healing is impaired by chronic inflammation and vascular dysfunction.
• Current electroceutical therapies face challenges with parameter optimization and device limitations.
• Modulating macrophage and cellular activity is crucial for transitioning wounds to a regenerative state.

Purpose of the Study:

• To identify optimal electrical stimulation (ES) parameters for chronic wound treatment.
• To develop a novel electroceutical patch for effective ES delivery.
• To evaluate the therapeutic potential of optimized ES via the patch in a diabetic wound model.

Main Methods:

• Screening of key ES parameters to attenuate inflammation and promote regeneration.
• Fabrication of a spray-printed conductive ink electroceutical patch (SCOPE) using PVA and LM.
• In vivo assessment of the SCOPE patch in a diabetic mouse wound model.

Main Results:

• Optimized ES parameters were identified to reduce inflammation and enhance regenerative processes.
• The SCOPE patch demonstrated stable and conductive ES delivery at dynamic wound sites.
• Application of the SCOPE patch suppressed inflammation and improved re-epithelialization and neovascularization in diabetic mouse wounds.

Conclusions:

• Optimized ES conditions effectively modulate immune responses for chronic wound healing.
• The SCOPE patch represents a viable therapeutic platform for delivering optimized ES.
• This approach shows significant potential for treating chronic inflammatory conditions and promoting tissue regeneration.
